Hello,

Do you have any idea what this chip might be ? You can find a picture with the two sides of it attached.

Thanks !   ^-^

IDT7209L - 12 x 12 Parallel CMOS Multiplier Accumulator

The datasheet is easy to find. 45C is a 45 ns MAC time, commercial temperature grade.

Nice. 30ns wasn't bad at the time for a 12x12 MAC. 40mA @5V.
Realize how spoiled we are these days.
